TIE-PLATE.

Specification of Letters Patent.

Patented Aug. 20, 1907.

Original application filed June 2, 1905, Serial No. 261%,488. Dividedand this application filed May 3, 1907. Serial No. 371,650.

To all whom it may concern: A

Be it known that I, WILLIs MCKEE, residing at Elyria, in the county ofLorain and State of Ohio, a

citizen of the United States, have invented or discovered certain newand useful Improvements n Tie Plates, of which improvements thefollowing is a specication.

In rolling tie plates having a transverse rib or abutment formed on itsupper face by a groove in the roll parallel with its axis, as describedand "claimed in an application for Letters Patent filed by me June 2nd,1905, Ser. No. 263,488, a bend is formed in the body of the plateadjacent to and parallel with the transverse abutment. This bend isbelieved to be due to the hanging of the abutment in the groove formedlongitudinal of the roll, for the formation of said rib during therolling of the plate. By reason of this bend howsoever formed, theHanges of the rails are unsupported along their outer edges, and whenthe head of the rail is subjected to an outward thrust, the rail willtend to rock on the plate and thereby tend to draw the spikes along theinner edges of the rails.

The invention described herein has for its object the production of atie plate of the type described with flat upper surface, so as to afforda uniform bearing for the rail ange.

The invention is hereinafter more fully described and claimed.

ln the accompanying drawings forming a part of this specification,Figure 1 is a sectional elevation of a rail and tie plate, the latterbeing bent as stated adjacent to the abutment, Fig. 2 is a similar viewshowing my improvement in tie plates; Fig. 3 is a sectional view ofrolls heretofore used showing the formation of the bend in thetie-plate;and Fig. 4 is a similar view showing a construction of rolls,whereby the tie plate can be formed with a straight upper or bearingsurface.

One of the rolls, preferably the upper roll A, is formed with one ormore grooves 2 parallel with the axis of the roll for the formation ofabutments 1 extendng across one side of the bar-plate. When it isdesired to make plates having a longitudinal rib or .ribs 3 on theunderside, the other roll B is formed with one or more peripheralgrooves, as indicated by dotted lines.

It will be observed by reference to Fig. 3, that the roll A hasheretofore been constructed of full'diameter except of the plate. p Inorder to overcome this defect, a portion of the roll immediately intherear of the groove 2 is cut away as shown, so that a swell orenlargement will be formed on the upper face of the plate correspondingn location to the depression heretofore produced. As the formation ofthe plate progresses, it is bent or distorted as heretofore, but if cutaway portion has been properly treated and proportioned a swell orenlargement Will be formed on the plate and the bending Will result inthe production of a plate having a straight upper surface. This bendingof the reinforced plate will cause the swell to appear on the oppositeor under side of the plate. As this swell or enlargement is slght, itwill not prevent the plate embedding itself firmly on the cross-ties,the swell being forced into the same.

It has been found in practice that wear of the plate is most rapidadjacent to the abutment, and hence the reinforcing of the plate asdescribed is desirable not only as it results n producing a plate whichwill afford a uniform support for the rail, but for the reason that itstrengthens the plate where the greatest Wear occurs.

I claim herein as my invention:

1. A rolled tie plate bar having a transverse abutment and longitudinalribs and having a straight flat upper surface.

2. A rolled tie plate bar having a transverse abutment and reinforcedadjacent to the abutment.

3. A rolled tie-plate bar having a transverse abutment and a straightflat bearing face for the .rail, and reinforced adjacent to theabutment.

4. A rolled tie plate having on one side a continuous abutment extendingtransversely of the plate and a longitudinal rib on the opposite side,said plate having a straight flat upper surface.

5. A rolled tie plate having a transverse abutment on one side and ribsextending longitudinally of the plate on the side opposite the abutment,said plate being reinforced adjacent to the abutment.

In testimony whereof, I have hereunto set my hand.

WILLIS MCKEE.
